Thread: 22 cal smoothbore vs rifled 22lr bore RE SHOT SHELLS

Hi All Had a smooth barrel made for testing 22 cal shot shells via a Rossi Monti a while back
have decided to now use this in a Lill Badger banger .. patterns are tighter but today i was just testing the effect of suppressors on pellet spread.
The 22 shot is loaded rather hot compared to a CCI std round fired through this barrel with a ASE Rimfire can fitted ..
My question to the most learned soles is which type of baffle ie flat washer vs K baffle vs sloping washer etc would have the least effect
on the shot spread . RE SHOT SHELLS have no cup wad so at the end of the muzzle they will spread ..
Thanks for looking
